# How to find point on a circle using a angle

Attention Topic was automatically imported from the old Question2Answer platform.

The way I am currently using is the “Unit Circle” aka

``````posOnCircle = vector2(offset + radius * cos(angle), offset + radius * sin(angle))
``````

The problem is this only works using degree calculations, which Godot does radian by standard. So I was wondering if there is a better way to do this with Godot, or at least how to make Godot calculate in degrees not radians.

Note: If you’re generating random points on a circle, you may want to support this proposal.

You can easily convert between degrees and radians at will via the following 2 utility functions:

``````var rads = deg2rad(deg)
``````

Yeah I tried that, but where would I put the rad2deg() in the equation

``````offset + r*cos(θ)
``````

Because on a calculator in degrees mode, 0+1cos(30) = 0.8660254038
But on Godot, rad2deg(0+1cos(30)) = 8.837957

Godot’s `sin()` and `cos()` functions expect radians. If the value you have is in degrees you’d want to convert that to radians prior to passing it to the `cos/sin` functions.

So, this:

``````cos(deg2rad(angle_in_degrees))
``````

For example, this:

``````print(cos(deg2rad(30)))
``````

Outputs this:

``````0.866025
``````

Thank you! It works now
